METHODOF APPLY,ING DYE-STUFFS TO FIBROUS MATERIALS.

SPECIFICATION forming part of Letters Patent No. 272,498, dated February 20, 1883.

.7 0 all whom it may concern:

Be it known that I, HENRY W. VAUGHAN, of the city and county of Providence, in the State of Rhode Island, have invented a certain new and useful Improvement in the Method of Applying Dye-Stuffs to Fibrous Material Suitable for Textile Fabrics; and I do hereby declare that the following specification is a true and exact description thereof.

In previous Letters Patent granted to me Decemberv30, 1879, No. 223,019, there is described a method of coloring fibrous material, consisting in mechanically incorporating into its fibers during the manufacturing processes a vehicle-powder charged with coloring-matter and an oleaginous constituentyand'in the previous Letters Patent granted to me May 24,

.1881, N0.'242,080, there is described a process of dyeing fibrous material which'consists in bringing into juxtaposition a dye-stufi' and a mordant by mechanically incorporating the same, either separately or together, into the fiber by the aid of a suitable vehicle-powder and an oleaginous constituent, and afterward causing the mordant and the dye to unite me chanically to form a fast color, reference to said Letters Patent being had for a more full description of the processes therein described.

My present improvement is a modification of the hereinbefore referred to patented processes; and it consists in first spraying a suitaable quantity of oleaginous or unctuous matter upon the fibrous material, sufficient in quantity and so distributed over the fiber as to enable a powder-vehicle charged with coloringmatter or mordant, or with both coloring matter and mordant in conjunction, to adhere to the surface of the fiber; and, secondly, in applying to the oiled fiber the powder-vehicle so charged. 7

It will be also within my improvement to apply -the powder-vehicle charged, as above stated, with coloring-matter or with mordant, or with both coloring-matter. and mordant, to the fibrous material and afterward applying to the fibrous material so treated the oleaginous or unctuous matter; and also it will be within my improvement to apply to the fibrous material separately but cotemporaneously the Application filed J nly 17, 1882. (No specimens.)

color or mordant charged powder and the ole aginous matter.

Aconvenient method of applying the oleaginous material preparatory to receiving the powder-vehicle charged with coloring-matter or with mordant, orwi'th both coloring-matter and mordant, is by means of an apparatus well known in the arts as an atomizer and a convenient time to apply the same to the fibrous material will be found to be when the fibrous material is in that stage of manufacture when it is'in theform of sliver and while it is between the railway-trough and railway-head. The amount of oleaginous material will depend upon the amount of powder-charged vehiclesay four ounces of oleaginous material to every.

pound of color.

To apply the color or mordant charged powder, I prefer'to use an air-blast, which can be obtained from any of the various blowing-machines known in the art. To the air-outlet is attached a pipe or trough-say nine inches square and two or three feet in length. The

fibrous material is made to pass in front of this pipe or trough in the form of a sliver over a wire-mesh-covered cylinder revolving in front of the aperture in the pipe, and so that the fibrous material will be held against the aperture during its passage acrossl the same. The

color or mordant charged powder may be sifted into the air-receiving aperture of the blowingmachine; or it may be applied to the sliver while the latter is in the trough, and be distributed upon the sliver by the air-blast without being borne by the blast through the blow ing-machine.

If the powder-vehicle charged with color or with mordant, or with both color and mordant, is to be applied to the fibrous material before the oleaginous matter is applied, or cotemporaneously with the application of the oleaginous matter, the same apparatus, consisting of an atomizer for the oleaginous matter and. a blowing-engine for the color or mordant charged powder,can be used, the only difference in treatment between the two cases consisting in the difference in time-when the oleaginous matter and the powder-vehicle are respectively applied. 7

fiber the coloring-matter, combined with a pul- 1 veruleut vehicle, as set forth.

2. The method of applying dyestufi's and their mordants to fiber suitable for textile fabrics, substantially as hcreiubefore described,

by spraying the fiber with oleaginous matter 20 and blowing upon said fiber the coloring-matter, combined with a pulveruient vehicle and a mordan t, as set forth.
